What is all matter is made of atoms and molecules that are in constant?
The total mass remain constant after a chemical reaction.
What is the law of constant mass in chemical changes?
Mass can neither be created nor destroyed in a chemical reaction
How an increase in temperature change the rate constant of a chemical reaction?
yes ofcourse!
What is the effect of pressure and concentration on Kc and Kp values?
Kc is the equilibrium constant of a chemical reaction related to concentrations. Kp is the equilibrium constant of a chemical reaction related to pressures. Generally, in normal conditions the effect of temperature is not so important.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What are Kp aND KC?
Kc is the equilibrium constant of a chemical reaction; Kp is the equilibrium constant of a chemical reaction at constant pressure.
What is the rate of a chemical reaction is?
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
What is all matter is made of atoms and molecules that are in constant?
The total mass remain constant after a chemical reaction.
What is the law of constant mass in chemical changes?
Mass can neither be created nor destroyed in a chemical reaction
What is constant during a chemical reaction?
Amount of energy because it can not be created or destroyed.
How an increase in temperature change the rate constant of a chemical reaction?
yes ofcourse!
What does the value of the equilibrium constant indicate?
When a chemical reaction reach the equilibrium she can not continue spontaneously.
What is the effect of pressure and concentration on Kc and Kp values?
Kc is the equilibrium constant of a chemical reaction related to concentrations. Kp is the equilibrium constant of a chemical reaction related to pressures. Generally, in normal conditions the effect of temperature is not so important.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Does the total amount of mass during a chemical reaction increase?
The total mass of the compounds remain constant.
Which statement describes the differences between chemical reactions and nuclear decay rates?
Nuclear decay rates vary, but chemical reaction rates are constant
How can a chemical reaction shift toward the desired direction?
You can make it shift, by Le Chatliers principle. Or. By Reaction Quotient method and comparing it against the Equilibrium constant.
